针对非同轴非轴对称非球面镜的加工问题，提出了一种采用可调梯度夹具的平行磨削方法。为三轴数控磨床研制了AGF。根据所提出的磨削系统，给出了磨削方法。为了保证加工精度，讨论了AGF磨削方法的主要加工误差及其补偿算法。仿真结果表明，AGF旋转误差是影响被加工工件轮廓误差的关键因素。实验结果表明，采用该补偿算法可提高加工精度。
To machine a noncoaxial nonaxisymmetric aspheric lens, a new parallel grinding method that employs a fixture with an adjustable gradient (AGF) is proposed. The AGF is developed for a three-axis computer numerically controlled grinding machine. The grinding method is presented according to the proposed grinding system. To ensure the machining accuracy, the main machining errors and the compensation algorithm are discussed for the grinding method using the AGF. Simulation results show that the AGF rotation errors are crucial factors affecting the profile error of the machined workpiece. Experimental results show that employing the compensation algorithm increases machining accuracy.
